The events prompted a bomb-squad callout and the evacuation of homes in the Bridal Path neighborhood of Simi Valley, 30 miles northwest of downtown Los Angeles.

It started with a call to police from the suspect's brother about the killing of their mother, a house fire, the discovery of a woman's body inside the home and calls from residents reporting a man driving through on a tractor firing a gun.

An autopsy was scheduled to be performed on the victim Monday.

Police shot the suspect when "the officers were confronted with a deadly force situation," the Simi Valley Police Department said in a press release.

"Based on the information that was being received by the 911 callers that a subject was actively shooting a firearm in a residential neighborhood, the heroic actions of the officers involved cannot be understated," the press release said.

Residences in the area were evacuated as a precaution as a bomb squad checked the home after the fire was put out.

The officers are home on paid administrative leave pending the outcome of parallel probes into the shooting by the Simi Valley Police Department and the Ventura County District Attorney’s Office.
